Transmission Engineer

The DWDM Transmission L2 Fault Management Engineer is responsible for handling advanced incident analysis, troubleshooting, and restoration activities across the optical transport network. The engineer provides second-level technical support for DWDM transmission platforms, ensuring high network availability, rapid fault resolution, and compliance with customer SLA and QoS requirements.

Key Responsibilities

L2 Technical Fault Handling

• Perform in-depth troubleshooting of faults on DWDM systems, ROADM nodes, transponders, muxponders, and OTN components.
• Analyze alarms, optical performance indicators (OSNR, BER, power levels), and service disruptions to identify root cause and service impact.
• Handle escalated incidents from L1/NOC teams and provide expert guidance for resolution.
• Execute remote corrective actions, re-routing, optical power balancing, and configuration corrections where permitted.

Incident & Escalation Management

• Create, update, and manage all L2 trouble tickets with detailed technical analysis.
• Escalate complex issues to vendor technical support teams, specialists, or Field Operations when necessary.
• Follow restoration progress and ensure timely resolution within SLA commitments.
• Provide incident updates and technical reporting to internal teams and customers.

Network Quality & Performance

• Perform correlation of alarms and performance data to identify systemic or network-wide optical impairments.
• Support preventive maintenance analysis through review of optical parameters, trends, and degradation indicators.
• Recommend corrective actions, optimization steps, or configuration improvements.

Operational Excellence

• Ensure full compliance with operational processes, documentation standards, and change-management procedures.
• Support planned maintenance activities, service migrations, and upgrades when required.
• Maintain up-to-date technical knowledge of DWDM platform features, software versions, and new capabilities.

Skills & Competencies

• Strong technical understanding of DWDM/OTN technologies, optical layers, wavelength management, and transmission principles.
• Hands-on experience with DWDM management systems, network management platforms, and optical monitoring tools.
• Ability to interpret optical measurements, including:
  • Power Levels
  • OSNR (Optical Signal-to-Noise Ratio)
  • Chromatic Dispersion and Polarization Mode Dispersion (PMD)
  • Forward Error Correction (FEC) Metrics
• Strong analytical and diagnostic abilities for complex transmission faults.
• Clear communication skills for explaining technical issues to internal and customer stakeholders.
• Ability to work under pressure in high-availability operational environments.

Profile Requirements

• Minimum 2–4 years of experience in Transmission/DWDM L2 Engineering or a similar environment.
• Deep knowledge of optical transport networks and DWDM technologies.
• Experience working in multi-vendor transmission environments is an advantage.
• Strong discipline in following operational processes and maintaining accurate documentation.
• Results-driven with a focus on meeting SLA commitments and service restoration targets.
• Team player with a strong sense of ownership, accountability, and responsibility.
